Standard 1: Atomic and Molecular Structure - 10% of Star Exam

The periodic table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure. As a basis for understanding this concept:

Strand 1A

State Standard:Students will know how to relate the position of an element in the periodic table to its atomic number and atomic mass.

Students Will Be Able To:Explain organization of the elements in periodic table according to their mass & chemical & physical properties as proposed by Mendelev & later modified by Moseley. I&E (12D): Formulate explanations using logic and evidence.

State Standard:How to use the Periodic Table to identify alkali metals, alkaline earth metals and transition metals, and trends in ionization energy, electronegativity, and the relative sizes of ions and atoms.

Students Will Be Able To:Recognize & identify the groups & periods on the periodic table and be able to predict the trends in ionization energy, electronegativity and sizes of ions and atoms based on their position in the periodic table.

State Standard:Spectral lines are a result of transitions of electrons between energy levels. Their frequency is related to the energy spacing between energy levels. Their frequency is related to the energy spacing between levels using Planck's relationship (E=hv).

Students Will Be Able To:

11/5/2018 NO HOMEWORK
BUT
What about your notebook that is due on Thursday? Look on my home page for link of how to do it. Don't wait until Wednesday night at midnight!!!!
126 points on the line!!!!!

11/1/2018 LINK - animation used in class today to help visualize why electrons in the ground state "jump" to higher energy levels and then return to the ground state.
